* Add locking where it was missing.

* Don't do a get_mtd_device in blktrans_open because it would lead to a
  deadlock; instead do that in add_mtd_blktrans_dev.

* Only free the mtd_blktrans_dev structure when the last user exits.

* Flush request queue on device removal.

* Track users, and call tr->release in del_mtd_blktrans_dev
  Due to that ->open and release aren't called more that once.

Now it is safe to call del_mtd_blktrans_dev while the device is still in use.

mtd: mtdblock: Dynamically allocate cache info structures 2010-02-25T11:53:00+00:00 Ben Hutchings bhutchings@solarflare.com 2010-01-29T20:58:37+00:00 cbfe93e9cedfcd59689bad9e67f57ef67545e5a0 Since we allocate struct mtd_blktrans_dev for each block device, we can add our own structure members to the end. Therefore embed struct mtd_blktrans_dev in struct mtdblk_dev and remove the static array of struct mtdblk_dev. Also remove the redundant pointer to struct mtd_info. This is preparation for removing the static limit on the number of MTD devices.
